Perspectives for early non-SUSY discoveries of physics beyond the Standard Model at LHC

Approaching the start-up of the Large Hadron Collider project, it is interesting to understand which possible processes could provide some evidence of physics Beyond the Standard model (BSM) with the first 1-100 fb${^-1}$ of integrated luminosity. Here we will not consider models based on Supersymmetry (SUSY); rather, between the plethora of non-SUSY models of physics BSM, we are going to go over two very promising classes of phenomenologies: Extra Gauge Bosons and Extra Dimensions.
